Packers wide receiver Davante Adams was taken off the field on a stretcher and left the stadium in an ambulance tonight after being the victim of a vicious hit from Bears linebacker Danny Trevathan. The hit—which was called as an unnecessary roughness penalty—sent Adams’s mouth guard flying as his head slammed into the ground.

Adams was able to give a thumbs up as he was taken off the field.

Update (11:45 p.m. ET): Adams has shown movement in all extremities now and is being evaluated for a concussion or further injuries.
